Default OS FS120 Surpass-E or FS110a

I just finished setting up a Phoenix Models Extra 330S 64" span with a OS FS91SII. This engine is sufficient for this airplane to do normal stuff but not for 3D. Originally, I was to put in a 120ax or a gas engine, the 91 was only temporary. But I like the way the 4C works so much, I am thinking to put in a FS110a or FS120E. Wanted to know a few things

1) The 110a does not have a crankcase breather. How does lubrication get to the crankcase?

2) The 110 is listed lighter than the 91 by a few grams. How come?

3) Does the FS120E also not have a nipple?

4) How does the 120E differ from the 120SIII? The latter is no longer available, is there a plan to replace the 120E with a newer model?

5) When will the 33size OS gassers be out?

What would be your recommendation in this regard?

According to O.S., the FSa-110 doesn't need a breather. Their design gets the oil to all vital parts.

2) The 110 is listed lighter than the 91 by a few grams. How come?

That's how it turned out.

3) Does the FS120E also not have a nipple?

The FS-120 Surpass E does have a breather.

4) How does the 120E differ from the 120SIII? The latter is no longer available, is there a plan to replace the 120E with a newer model?

The FS-120 Surpass III is a pumped engine, the FS-120 Surpass E is not. The FS-120 Surpass III is not discontinued, and can be purchased from your favorite O.S. retailer.

5) When will the 33size OS gassers be out?

Sometime in the Fall.

What would be your recommendation in this regard?
